Structural Map Volatility Breakout
Family: volatility · Regime: trending · Complexity: medium · Asset classes: FX, Indices, Commodities · Timeframes: H1, M30
Thesis
Market momentum is often signaled by a breakout where the current bar's range (True Range) significantly exceeds its historical average (ATR), especially when price sustains a level above its drift-adjusted previous close. By anchoring exits to session-based volatility projections (ATR Fib) and tying risk to real-time transaction costs (Spread), the strategy captures high-velocity moves while avoiding low-liquidity traps.
Components
- MQL5 Structural Sample Logger (regime) — Used as a 'data integrity' regime filter; trades are only permitted when the OnCalculate event loop confirms a stable history (prev_calculated > 0) and sufficient bar count for ATR calculation.
- Supported map history demonstration (direction) — Provides the trend bias. By comparing current price to the previous close adjusted by the map's historical size, it creates a dynamic, upward-drifting threshold for momentum confirmation.
- Volatility Ratio (VR) (entry) — Identifies 'volatility ignition' events where the current bar's range significantly exceeds the average, suggesting a high-probability breakout.
- ATR Fib (exit) — Provides session-anchored profit targets and reversal levels based on fixed ATR projections from the session's high-open.
- Spread Display and Alert (risk) — Governs the trade execution quality. Sets a hard limit on entry spread and defines the Stop Loss distance as a multiple of the current cost of carry.
Known failure conditions
- ATR Fib manual ATR input (e.g., 250) becomes obsolete due to a 50% change in actual market volatility.
- Map size grows to a value that creates an insurmountable bias, preventing short signals indefinitely.
- Broker spreads consistently exceed the 'AlertIfSpreadAbove' threshold, resulting in zero execution.
